Realistic stereo recordings require microphones with outstanding performance and excellent quality. They also require performance consistency and accurate localisation from the pair of microphones. Therefore, every factory-matched pair has been created from thousands of individual microphones selected by AKG&apos;s sophisticated computer-aided matching method. The result is the highest possible correlation over the whole frequency range and virtually identical sensitivity for stunning, three-dimensional recordings.

The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 300 Hz to 8,000 Hz of the individual frequency response when used in cardioid mode. The microphones are selected from a large quantity of individual microphones according to the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings in various techniques will provide a good and stable balance without frequency-dependent shifting of the stereo panorama.
